Answer:
Following are the solution to the given question:
import java.util.Scanner;//import package
public class AscendingAndDescending//defining a class AscendingAndDescending  
{
    public static void main(String[] args) //main method
    {
        int n1,n2,n3,min,max,m;
        Scanner in = new Scanner(System.in);//creating Scanner class object
        System.out.print("Enter an integer: ");//print message
        n1 = in.nextInt();//input value
        System.out.print("And another: ");//print message
        n2 = in.nextInt();//input value
        System.out.print("And just one more: ");//print message
        n3 = in.nextInt();//input value
        min = n1; //use min variable that holds value
        max = n1; //use mix variable that holds value
        if (n2 > max) max = n2;//use if to compare value and hols value in max variable
        if (n3 > max) max = n3;//use if to compare value and hols value in max variable
        if (n2 < min) min = n2;//use if to compare value and hols value in min variable
        if (n3 < min) min = n3;//use if to compare value and hols value in min variable
        m = (n1 + n2 + n3) - (min + max);//defining m variable that arrange value
        System.out.println("Ascending: " + min + " " + m + " " + max);//print Ascending order value
        System.out.println("Descending: " + max + " " + m + " " + min);//print Descending order value
    }
}
Output:
Enter an integer: 8
And another: 9
And just one more: 7
Ascending: 7 8 9
Descending: 9 8 7
Explanation:
In this program inside the main method three integer variable "n1,n2, and n3" is declared that inputs value from the user end and also defines three variable "min, max, and m" that uses the conditional statement that checks inputs value and assigns value according to the ascending and descending order and prints its values.
